针对目前辽河油田一些主力的注水油藏地层压力与注采比不匹配的现象,根据矿场经验统计和理论分析,在水驱油动态方程基础上,推算出沈625块、沈67块等油藏的合理注采比,同时结合动态分析方法和物质平衡方程对潜山油藏的注采比进行了确定,与区块实际注采比进行比较,分析其影响因素,并提出下步注水方向。该研究对于油藏精细注水、有效注水具有一定的指导意义和实用价值。
In view of the phenomenon that the formation pressure and injection-production ratio of some main waterflooding reservoirs in Liaohe Oilfield do not match at present, based on the statistical and theoretical analysis of mine experience, based on the dynamic equation of water flooding, Shen 625 block and Shen 67 block oil are calculated The ratio of injection to production of buried hill reservoirs with dynamic analysis method and material balance equation is determined and compared with the actual injection-production ratio of the block, the influencing factors are analyzed and the direction of next injection is proposed . The study has certain guiding significance and practical value for fine water injection and effective water injection.
